No, these are sent by Siemens IP routers to the multicast.
Note that we didn't use standard multicast due to multiple KNX installations at the same network (customer requirement).
But both IP routers and LM5s are set up with the same multicast address.
It might be worth mentioning that we use GA filtering to filter away group addresses we don't use. But I got same issue without filter.
